This bag is really big and deep. It has a large inside pocket and two side pockets, all closable with zip. Inside there as a small resealable pouch with Velcro (to put keys or phone, for example), but pity there is only one.
There are two ways to wear it, either arm (reinforced by a scratch for better grip) or either shoulder. The shoulder strap is reinforced and can be removed if desired.
The slides are correct.
The seams are finished and look strong.
The logo is flocked and is fairly unobtrusive.
The bottom of the bag is protected by an impermeable coating (perfect for the pool, for example!).
I do have some complaints. First of all I do not like the chemical smell unpacking, then I think it lacks a reinforcement in the background (it makes it too soft), and finally there is light enough in its materials. I confess that I will have thicker may be desired ...
It's a sports bag for casual use, I do not advise to big sporting that make everyday but for those like my husband have a small weekly sports activity.
Eventually, it can be used during weekend, if you do not load too much.
Now to be seen in the long term solidity?
In summary, this bag is well thought overall. It is quite correct for the proposed price (19.90 in my review).
It will be ideal for occasional sports or for a small weekend.
